GUN-CARRIAGE.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, NORIIERT Kocir", a subject of the Emperor of Germany, and a resident of it .-,\.uguslas irasse, Essen-on-th'e- Ruhr. Germany, have invented; certain new and useful Impmvements in Gun-Carriages, of which the following is a specification. j

The present invention relates to gun earriages of the type disclosed in my United States Patent No. 912,135 andthe main object of the invention is to provide thisdype of gun carriages with a brake by means of which the wheels can be secured in the training position.

The accompanying drawings show an embodiment of the 1I1VI1t10l1,"by way of example.

Figure l is a side view, partly in section, of a gun carriage, one wheel being broken away and the other wheel being in the train 4 ing position; Fig. 2 is atop view of Fig. 1;

Fig. 3 is a front view of Fig. 1, the wheels being shown diagrammatically; Figs. 4. to 7 are sections, on an enlarged'scale, on line &4;, Fig. 2, and showing different positions of the parts; Fig. 8 is a part of Fig. 2 showing the parts in a different position, and Fig, 9 is a top View showing the wheels in the traveling position.

A indicates the carriage body which has its trail provided with a spade B which can turn about a vertical axis. The wheel-axle C is secured in the other end of the carriagebody A and terminates in two bifurcated pieces C between which the spindles 1) of the carriageovhecls 1* are mounted to swing in horizontal planes through the medium of l The bolts D can turn lnthe bi bolts 1). furcated pieces C but they are nou-rotatably secured to the spindles D. The wheels E are mounted on the spindles D. Below each piece C is arranged an angle-piece F, F which is nonrotatably connected with the bolt D by means of a square. The arms of these angle-pieces are bent toward the axle C and are each provided with a bore f and f By'swinging the wheels E these bores can be brought into register with bores 0 in the axle C. The angle between the 1 arms F and F is selected in such a manner that the wheels can assume either the position required for travel or the HPOSIUUU required for training, according to whether.v the bores a register with the bores f or With.

the bores In the training position of the y wheels the. axes of rotation of the wheels l intersect the axis of rotation of the spade B. By means of "bolts G, which are slidable in the bores 0 the anglepieces F, F and consequently also the spindles D, can be coupled to the axle C in either of these positions.

011 the front of the carriage-body A a shaft H is'journ'aled in bearings a and a which shaft can be turned about its longitudinal axis within certain limits through the medium of a hand-lever H which is rigidly secured to the shaft H. The hand-lever H can yield laterally and slide along an arcuate rail J which is rigidly secured to the axleC and which is provided with stops 2' and 4' which limit the movement of the hand=leven 'Notches i 2' in the rail permit of securing the lever H in different positions to be described in the following. On the front of the'carriage-body A is secured a :bcaring-arm M which is located at the same elevation as the axle C. A plate K can slide in the arm M in the longitudinal direction of the carriage-body A. On the outer end of the plate K are secured two wedge-shaped brake-shoes K and K which can become lodged between the Wheels E when the latter are swung into the training position. A one-armed lever H 'is mounted on the shaft Hwhich lever is provided with g a bolt A which engages in a vertical slot k in the plate K (see especially Fig. 4) so that, when the lever If is turned, the plate K moves in the direction of the longitudinal axis of the carriage. Two additional onearmed leversll which are keyed on the shaft ll are provided with heads [i which engage in recesses g provided in twoZ- shaped slides Gr. These slides are connected with the bolts G in such a manner that, when 'itheshaft It turns. the bolts Gr move vertically fiS-SliOWll in Figs. l; to 7. The mode of operation of the device is as follows: In the traveling positionof the wheels the parts assume the position shown in Figs. Tiand 9; the hand-lever H is turned 1 back to the stop on the rail J and rests in the notch provided in the rail at that place. In this position of-the lever H the lowermost position in which they engage in the bores f in the angle-pieces F, F. and couple the spindles l) to the axle (1 through the medium of the angle-pieces F, F and the bolts l). The plate K with the brakeslide Gr causes the bolts G- to assume their the same time the levers H and the slides G firmly pressed against the two wheels E and position, and means movable into engageshoes K and K are .then held toward the 1 rear by the lever H and the guide h 70 to i such an extent that the brake-shoes abut-i against the bearing-arm M. If it is desired to swing the wheels into the training posi- Y tion the lever H? is shifted forwardly until it reaches the stop 2' as shown. in Fig. 5. \Vhile this takes place the lever H and the guide h k causes the brake-shoes to be moved into their foremost position and at cause the bolts G to move upwardly and pass out of the bores Pin the angle-pieces F, F thereby releasing the coupling between the spindles D and the axle C. The wheels can then be swung into the training position; When the wheels have been swung into the training position (see Fig. 8) the lever H is moved rearwardly until it snaps into the notch i in the rail J (see Fig. 6) and this mo ement of the lever causes the bolts G to move so far downwardly that they efiect the coupling between the spindles D and the axle C and simultaneously herewith the brake-shoes K and K have moved into the position shown in Fig. 8 relative to the wheels. The carriage can now be swung within any desired limits about its rotatable spade to obtain the .rough lateral adjustment or training. When this has been done the lever H is moved farther rearwardly (see Fig. 4) until the brake-shoes K and K are secure the wheels against rotation (see Fig. 2). In order to hold the lever H in this position the rail J is provided with a plurality of notches i to allow for wear of the brake-shoes and the tires of the wheels. In this position of the lever H (Fig. 4) the bolts G extend farther down into the'bores 3 of the angle-pieces F, F than they do ghen the lever H is in the position shown in ig. 6. I

Having thus described'the invention what is claimed and desired to be secured by Letters Patent is l. A gun-carriage having a spade mounted to rotate about a vertical axis, carriage- A wheels adapted to be swung ablout vertical axes from a traveling position to a training ment with both of said wheels when in their training position to prevent rotation of the wheels.

'2. A gun-carriage having a spade mount ed to rotate about a vertical axis, carriage wheels adapted to be swung about vertical axes from a traveling position to a training position, and means movable into engagentent with both of said wheels when in their training position to prevent rotation of the wheels, said movable means comprising a brake mounted on the carriage and movable in the longitudinal direction of the earriage.

A gun-carriage having a spade mounted to rotate about a vertical axis, carriagewheels adapted to be swung about vertical axes from a traveling position to a training position, and means movable into engagement with both of said wheels when in their training position to prevent rotation of the wheels, said movable means comprising a wedge-shaped braking member movable" in, the longitudinal direction of the-ca riageand adapted to be pressed 'against thefadja cent surfaces of-the wheels when thewheels' are in the training position.

4. A gun-carriage havmga spade mounted to rotate about a vertical axis, carrlagewheels adapted to be swung about vertical axes from a traveling position to a training position, spindles upon which the wheels are rotatably mounted, means for coupling the spindles to the carriage in either of said positions of the wheels, braking means movable into position between said wheels to prevent rotation of the wheels when in their training position, and means positively connecting said braking means and said coupling means in such a manner, that when the brake is released the coupling between the spindles and the carriage. is either released or efiected, while when the brake is set the-coupling is always effected.
